Operation & Maintenance of Power Plants
training simulators for the Shoaiba II combined cycle power plant, which is being built in the Kingdom of Saudi Arabia (KSA) for the Saudi Electricity Company. Located south of Jedda on the Red Sea coast,
Shoaiba II will have ten gas turbines and two steam turbines with a combined output of 1200 MW (two blocks of 600 MW each) and is scheduled to start operation in June this year. Te order was placed by Daelim Industrial
and covers a comprehensive solution comprising a CENTUM VP control system and a simulator which will be used to train operators under complex simulated plant operating conditions. Te control system at the plant will be for the integrated control of heat recovery steam generators (HRSGs) and gas turbines. For the systems and products that make up these solutions, Yokogawa Middle East and its subsidiary Yokogawa Saudi Arabia will be responsible for project execution, including engineering, testing, installation and commissioning. Yokogawa Middle East says it was able to secure
this order due to factors such as its top platinum rating for ‘Saudisation’ under the Saudi government’s Nitaqat programme. Tis began in 2007 with the establishment of two Yokogawa companies, Yokogawa Saudi Arabia and Yokogawa Services Saudi Arabia, to provide sales, engineering, and after sales services in the KSA. Also taken into consideration were Yokogawa’s activities to promote professional education and provide employment in the country.
Te company also points to additional contributing factors such as the engineering capabilities acquired since 2007, the close project support afforded through the global cooperation of the Yokogawa Group and the high functionality of its plant simulation solution for control function testing and operator training. Encouraged by its success in being awarded this contract, Yokogawa says that it now aims to expand its
controls business in the KSA by further targeting the power plant sector and other energy-related markets.
Indian coal power Alstom Bharat Forge Power (ABFPL), the joint venture company between Alstom and Bharat Forge, has secured in India an order worth over €350 million to supply three units of 660 MW supercritical coal turbine islands to Nabinagar Power Generating. Tis is a joint venture between NTPC and Bihar State Electricity Board in Nabinagar, located in the state of Bihar.
ABFPL’s scope of work includes engineering, manufacturing, supply, erection and commissioning of three 660MW supercritical units. Tis order is part of the NTPC bulk tender for the supply of 11,660MW turbine generator islands. Tis award follows the €250 million order won by ABFPL in April 2012 for the supply of two 660MW supercritical units to NTPC Solapur site in Maharashtra, India. Alstom’s supercritical technology uses steam with
very high temperatures and pressure, resulting in a much higher efficiency (above 40 per cent) than conventional sub-critical coal fired plants. Tis means that a supercritical unit burns much less coal. In the USA, Fluor Corporation has won a five-year contract from Oklahoma Gas and Electric (OG&E) to provide maintenance and construction services for all seven of its power generation plant sites in Oklahoma. Te value of the contract was undisclosed. Te contract involves Fluor supplying supervision and craft personnel to support ongoing base crew maintenance as well as major outage and project work, construction services and plant modifications. AMECO, Fluor’s equipment, tool and fleet management unit, will provide complete craft support services at all OG&E project site locations associated with this contract. ●

Contract operation and maintenance For example, the company is currently
ontract operation and maintenance services need to provide all the personnel and
management systems necessary to safely commission, manage, operate, maintain, and administer the business and technical aspects of a power generating facility. Over the years, Sterling Energy has gained experience and expertise operating a wide range of plant types including biomass, combined cycle combustion turbine, cogeneration, and aeroderivative-based peakers. The company has operated those plants in a variety of business contexts and so has built up a familiarity with merchants, power purchase agreements, and tolling.

commissioning and will operate a combustion turbine cogeneration plant in Canada. The plant includes two LM6000
combustion turbine generators and two once-through steam generators. The cogeneration facility will sell energy into the Ontario merchant market and will provide steam to the Ford Motor Company. In addition to mobilising and
operating the new facility, Sterling Energy will continue to manage the adjacent Ford power plant – a situation that has been ongoing since 2007. “We understand that the mission of
every power plant business is two-fold. First, to provide exceptional returns to the investors by seeking every reasonable opportunity for increased revenues and reduced expenses, while optimising the balance between them. Second, preserve the value of the plant through cost-effective maintenance and the improvement of its human and physical assets,” says the company. Sterling says it also recognises that
each step in the evolution of a power plant – from the development phase through maturity – presents a unique set of management issues, priorities, dangers, and needs for critical management systems. ●
